This application claims priority to U.S. Provisional Application Ser. No. 62/484,697, filed on Apr. 12, 2017, the entire contents of which are hereby expressly incorporated herein by reference.
Water sports using boats are increasingly popular for water sport practitioners. Such water sports may include, for example, water skiing, water tubing, wakesurfing, and wakeboarding. Riders in the boat pulling the water sport practitioner may want to add an additional activity such as the use of a boat spray gun to spray water at the water sport practitioner or others.
However, there are problems encountered when attempting to provide a supply of water to a boat spray gun while the boat is moving. First, boat owners may not want to cut additional holes through the boat to access water for the spray gun. Second, existing ports may be undesirable for accessing the water. For example, current access from the boat to the water may be found through a drain port in the stern of the boat. However, when a boat is in motion, a low pressure region forms behind the boat such that water near the drain port may have negative or zero water pressure, which makes water intake at that location difficult. Third, scoop systems alone do not create enough pressure for effective spray gun use. Therefore, apparatuses and systems are needed to intake water from the outside of the boat for use with a boat spray gun, using existing ports through the boat hull.
The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate one or more implementations described herein and, together with the description, explain these implementations. The drawings are not intended to be drawn to scale, and certain features and certain views of the figures may be shown exaggerated, to scale or in schematic in the interest of clarity and conciseness.

As used herein, the terms “comprises,” “comprising,” “includes,” “including,” “has,” “having” or any other variation thereof, are intended to cover a non-exclusive inclusion. For example, a process, method, article, or apparatus that comprises a list of elements is not necessarily limited to only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Further, unless expressly stated to the contrary, “or” refers to an inclusive or and not to an exclusive or. For example, a condition A or B is satisfied by anyone of the following: A is true (or present) and B is false (or not present), A is false (or not present) and B is true (or present), and both A and B are true (or present).
In addition, use of the “a” or “an” are employed to describe elements and components of the embodiments herein. This is done merely for convenience and to give a general sense of the inventive concept. This description should be read to include one or more and the singular also includes the plural unless it is obvious that it is meant otherwise.
Further, use of the term “plurality” is meant to convey “more than one” unless expressly stated to the contrary.
As used herein, qualifiers like “substantially,” “about,” “approximately,” and combinations and variations thereof, are intended to include not only the exact amount or value that they qualify, but also some slight deviations therefrom, which may be due to manufacturing tolerances, measurement error, wear and tear, stresses exerted on various parts, and combinations thereof, for example.
